Specification of Letters Patent.

Patented Jan. 11, 1910.

Application filed July 2, 1909. Serial No. 505,540.

T 0 all whom it may concern:

Be it known that I, GEORGE K. GARRETT, a citizen of the United States,and a resident of the city of Philadelphia, State of Pennsylvania, haveinvented certain new and useful Improvements in Umbrellas, of which thefollowing is a full, clear, and complete disclosure, reference being hadto the accompanying drawings, forming part of this specification.

The main objects of this invention are, to provide a simple andinexpensive joint between an umbrella rib and a stretcher, that will becompact, strong, and durable, and in which a relatively large rivet maybe used for connecting the rib and stretcher without increasing the sizeof the joint or weakening the rib; to provide an umbrella rib or othergrooved member with an eye of simple, strong, and durable constructionto receive fastening means; to provide a pivoted connection between arib and a stretcher in which the rib is not pierced by the pivot butretains its full original strength, and in which no portion of the jointprojects from that side of the rib that comes into contact with theumbrella cover, thus avoiding the necessity of a protecting piece ofmaterial between the joint and the cover, and consequently improving theappearance of the umbrella and reducing its cost; to provide an improvedlow connection between a rib and a stretcher, or, in other words, aconnection in which the axis of movement between the parts is relativelyclose to the longitudinal axis of the rib, thus adapting the connectionto form a close rolling umbrella; and to provide other improvements aswill appear hereinafter.

In the accompanying drawings, Figure l is a side elevation of anumbrella rib and stretcher connected in accordance with this invention.Fig. 2 a top plan view of the same; Fig. 3 a central longitudinalsection of the same; Fig. .t a side elevation of the rib with thestretcher removed; Fig. 5 a transverse section on line 55 of Fig. 1; andFig. 6 a transverse section on line 6-6 of Fig. 1.

Referring to the drawings, one embodiment of this invention comprises acorrugated or longitudinally grooved rib 1, substantially U-shaped incross section throughout the greater portion of its length, and

a corrugated or longitudinally groove-d stretcher 2, substantiallyU-shaped in cross section and having a. bifurcated end forming ears 3which embrace the sides of the rib. The open side of the stretcher 2 isturned toward the open side of the rib 1 when the umbrella is in use,and the inside dimensions of the stretcher are greater than the outsidedimensions of the rib, so that when the two parts are closed togetherthe stretcher will incase the rib.

For connecting the rib 1 and the stretcher 2 a short piece of wire t isbent centrally or intermediate of its ends to form a loop 5, and theends 6 of the wire are arranged longitudinally within the rib 1, thediameter of the wire being preferably substantially the same as theinside diameter of the rib so that the ends of the wire fit snuglywithin the rib. For holding the wire securely in position in the rib 1,the sides of the rib adjacent each end of the wire are turned inwardlyto incase each end of the wire as at 7. Each end of the wire is thustightly held in a cylindrical casing formed by the rib. The loop 5 ofthe wire t forms the outer half or portion of an eye 8, the innerportion of which is formed by bending inwardly the sides of the rib 1opposite the loop 5, as at 8, the opposite edges of the rib being thusbrought into abutment centrally of the eye, and the inwardly turnedportions of the sides of the rib forming the inner half of the eye beingthus bent inwardly around the inner portion of the loop 5.

The stretcher 2 is connected to the rib 1 by means of a rivet 9, whichextends through apertures provided therefor in the ears 3 of thestretcher and through the eye formed by the loop 5 and the inwardlyturned sides of the rib, each end of the rivet being upset, as usual, toform a head 10 outside of the adjacent ear 3. By this means a relativelylarge rivet 9 may be used, supported by the relatively broad bearingsurfaces of the eye 8, and a simple, strong, and durable joint is thusprovided between the rib 1 and the stretcher 2.

Although only one form has been shown in which this invention may beembodied, it is obvious that many changes might be made in theconstruction illustrated without departing from the spirit of thisinvention or the scope of the appended claims.

Having thus fully described my invention, I claim and desire to protectby Letters Patent of the United States:

1. The combination with a rib having a longitudinal groove, of a wireprovided intermediate of its ends with a loop and having its ends fittedwithin the said groove, the sides of the rib being bent inwardly aroundeach end of said wire to hold the wire in position, and inwardly withinthe loop to torm the inner portion of an eye, the outer portion of saideye being formed by said loop, a stretcher, and a pivot extendingthrough said stretcher and said eye.

2. The combination with a rib, having a lon itudinal groove, of a wireprovided intermediate of its ends with a loop and having its ends fittedwith said groove, the sides of the groove being bent. inwardly aroundeach end of said wire to hold the wire in position, and the sides of therib being bent inwardly within said loop to form the inner portion of aneve, the outer portion of which is formed by said loop.

3. The combination with a rib having a longitudinal groove, of a wireprovided intermediate of its ends with a loop and having its ends fittedlongitudinally within said 'roove. the sides of the rib within the loopbeing bent inwardly into abutment to form the inner portion of an eye,the outer portion of which is formed by said loop.

l. The combination with a rib substantially U-shaped in cross sectionfor part of its length, of a wire provided intermediate of its ends witha loop and having its ends fitted longitudinally within said rib, thesides of the rib being bent inwardly within the loop to form the innerportion of an eye, the outer portion of said eye being formed by saidloop.

5. The combination with a corrugated rib, of a wire providedintermediate of its ends with a loop and having its ends fitted withinsaid rib, the sides of said rib being bent inwardly to form the innerportion of an eye, the outer portion of said eye being formed by saidloop.

6. The combination with a corrugated rib, of a wire providedintermediate of its ends with a loop and having its ends fitted withinsaid rib, the sides of said rib being bent inwardly into abutment toform the inner portion of an eye, the outer portion of said eye beingformed by said loop.

7. The combination with a rib having a longitudinal groove, of a wirebent intermediate of its ends to form a loop and having its ends fittedwithin said groove, the sides of said rib being bent inwardly adjacenteach end of said wire to hold said wire in position, and the sides ofsaid rib being bent inwardly into abutment within said loop to form theinner portion of an eye, the outer portion of which is formed by saidloop, a stretcher having a longitudinal groove, and a bifurcated endforming ears embracing said rib, and a rivet extending through said earsand said eye forming a pivotal connection between said rib and saidstretcher.

8. The combination with a rib having a longitudinal groove, of a wirebent intermediate of its ends to form a loop and having its ends fittedwithin said groove, the sides of said rib being bent inwardly adjacenteach end of said wire to hold said wire in position, and the sides ofsaid rib being bent inwardly into abutment within said loop to form theinner portion of an eye, the outer portion of which is formed by saidloop, a stretcher having a longitudinal groove and a bifurcated endforming ears embracing said rib, and a rivet extending through said earsand said eye forming a pivotal connection between said rib and saidstretcher, the open side of said rib being turned toward the open sideof said stretcher when said rib and stretcher are in operation, and theinside diameter of said stretcher being slightly greater than theoutside diameter of said rib, whereby said stretcher will incase saidrib when the two parts are brought together.

In witness whereof, I hereunto set my hand this 30th day of June A. D.,1909.
